Regarding IT security, every little element counts. Among the several tools and methods at hand, network logs and HTTP status codes are quite important in spotting and reducing security risks. Usually disregarded, these two elements can offer insightful analysis of the security and health of your network architecture. Knowing how to make best use of them will greatly improve the security situation of your company.
HTTP Status Codes: The First Line of Defense
Three-digit responses given by a server in response to a client’s request make up HTTP status codes. Five classes define these codes: informative (100-199), success (200-299), redirection (300-399), client errors (400-499), and server errors (500-599). Every status code offers a particular message regarding the result of the HTTP request, which may be quite useful for keeping an eye on and protecting your IT setup.
High frequency of 403 (Forbidden) or404 (Not Found) errors, for example, can point to possible reconnaissance operations by hostile actors seeking to access limited portions of your network. Likewise, 500-level errors like 502 (Bad Gateway) or 503 (Service Unavailable) could point to underlying server problems that, if not quickly fixed, could be used advantageously. Regular monitoring these HTTP Status Codes helps IT teams find odd trends that can point to a vulnerability in the system or an ongoing attack.
Network Logs: The Backbone of Security Monitoring
Although HTTP Status Codes present a high-level perspective of server answers, network logs give a more detailed insight of the activity running inside your network. Including IP addresses, timestamps, and the type of the data being transferred, network logs preserve minute details of traffic passing through the system. Investigating possible security events and spotting suspicious behaviour depend much on this information.
Examining network logs helps IT experts follow an attack’s path, spot compromised devices, and comprehend attacker techniques. Early signs of a security breach, for instance, can be odd traffic spikes or connections to known dangerous IP addresses. Additionally useful for spotting internal hazards like staff members accessing private data without permission are network logs. Network logs allow one to piece together the chronology of an attack using the correct tools and knowledge, therefore offering a clear picture of how the breach happened and what actions should be taken to stop next ones.
Integrating HTTP Status Codes and Network Logs for Proactive Security
HTTP Status Codes and network logs have real power only in their interaction. These instruments taken together can offer a whole picture of the security scene of your network. For instance, matching 403 errors with network logs displaying repeated failed login attempts from the same IP address will rapidly identify a brute-force attack under way. Likewise, HTTP Status Codes can be cross-referenced with network logs displaying data exfiltration attempts to find whether the server blocked or successfully completed these efforts.
Proactive security depends on HTTP Status Code and network log monitoring being automated. Modern security information and event management (SIEM) systems can be set to notify IT teams should specific trends or anomalies in these logs be found. Real-time responses to possible hazards made possible by this help to lower the time required to identify and handle security breaches.
Best Practices for Leveraging Logs and Status Codes
Following these best practices will help companies to utilize the security advantages of HTTP Status Codes and network logs. First make sure network logs are kept for enough time to enable comprehensive analysis and that all HTTP requests and answers are recorded. Frequent log audits help to spot and fix any security problems.
Second, where at least feasible apply automation. Manual research is usually unworkable given the volume of data produced by HTTP Status Codes and network records. Automated tools can highlight the most important security events and assist to filter noise.
Security teams should thus be equipped to comprehend and evaluate the data given by network logs and HTTP Status Codes. Effective security monitoring depends on a knowledge of typical attack patterns and the capacity to link data from several sources.
Conclusion
Every instrument you have at hand is useful in the battle against cyberthreats. Network logs and HTTP status codes provide special information that, taken in concert, will significantly improve the IT security in your company. Understanding these technologies and including them into your security plan can help you to identify risks early on, react more precisely, and finally save your network more successfully.
